en, basiclly, our project needs a window manager and we want to use an existent one. semi-transparency is also a high-priority feature.� hope clear now why i want DirectFB+GTK+XDirectFB
No. Not clear. First: If you use DirectFB+"GTK for DirectFB" you dont need XDirectFB. So please forget XDirectFB for your embedded applications.
Second: If you just want transparent managed windows you can also get rid of GTK by using lite. (or manage the windows on your own).
